I bought a 150 and 160 r-pro boss. I like the feel and they are not as floppy as the dart. I think they will be a great disc for those open field drives. I hear they can get beat up rather quickly though but at 12 bucks a shot they are not that expensive. I still like the FLX plastic better by discraft but I see this disc having a place in my bag.
I love my 161g and 159g R-Pro Boss. Slight hyzer flip and glides a long way. Gets nicked really easy, but a towel sands it down easy. My 150g and 141g are way too under stable. Don't throw them anymore. May keep them for altitude though.
I now putt with the R-Pro Aviar P&A (no bead). Great soft feel and goes real straight. Replaced my JK Aviars (not soft like they used to be), and Omega super softs.
Anyone throw the R-Pro Destroyer or Xcaliber yet? These may be sweet too!
